ESPN's Tom Luginbill has selected five freshmen who are enrolling this summer that he thinks will make an immediate impact in the fall.
Two of the players on his list will be playing in the SEC -- Ole Miss defensive end Robert Nkemdiche and Auburn defensive end Carl Lawson.
Nkemdiche was ESPN's No. 1 prospect nationally in the 2013 class. He was also the No. 1 defensive end. Lawson was the No. 2 defensive end nationally.
Ole Miss and Auburn were both in the bottom half of the league last season in pass efficiency defense, so adding a couple of dynamic pass-rushers should help both the Rebels and Tigers.
Here's a glance at a few other freshmen to watch in 2013 who will be enrolling this summer:
Jonathan Allen, OLB, Alabama: Ranked No. 28 in the 2013 ESPN 150, the 6-foot-3, 245-pound Allen is a hybrid defensive end/outside linebacker who should be a perfect fit in the Tide's 3-4 defense and add some pop to their pass rush.
Kendell Beckwith, LB, LSU: Ranked No. 41 in the 2013 ESPN 150, the 6-foot-3, 225-pound Beckwith is a tackling machine, and the Tigers will be looking for a couple of young guys to come in and play at defensive end and linebacker next season.
Alex Collins, RB, Arkansas: Ranked No. 57 in the 2013 ESPN 150, the 5-foot-11, 207-pound Collins was a huge get for Bret Bielema out of South Florida and has the tools and physical makeup to be one of the Hogs' rushing leaders as a freshman.
LaQuivionte Gonzalez, WR, Texas A&M: Ranked No. 111 in the 2013 ESPN 150, the 5-foot-10, 160-pound Gonzalez is a blur in the open field and should excel as the Aggies' slot receiver. He's also electrifying in the return game.
Vernon Hargreaves III, CB, Florida: Ranked No. 3 in the 2013 ESPN 150, the 5-foot-11, 185-pound Hargreaves is the kind of talent who could walk onto campus and be in the starting rotation from Day 1.
Chris Jones, DE, Mississippi State: Ranked No. 46 in the 2013 ESPN 150, the 6-foot-6, 260-pound Jones specializes in getting to the quarterback, which was a problem for the Bulldogs last season.
MarQuez North, WR, Tennessee: Ranked No. 133 in the 2013 ESPN 150, the 6-foot-4, 214-pound North is somebody the Vols are counting on to come in and play right away. They were depleted at receiver last season.
Shag Wiggins, CB, Georgia: Ranked No. 39 in the 2013 ESPN 150, the 5-foot-10, 170-pound Wiggins could join fellow freshman Tray Matthews in the Bulldogs' starting secondary. He'll be in the mix at both cornerback and nickel.
